Polyvinylpyrrolidone/PVP with Cas 9003-39-8
What is Polyvinylpyrrolidone/PVP?
The polyvinylpyrrolidone (Povidone) series, including K15, K17, K25, K30 and K90, are high-quality pharmaceutical excipients that meet EP and USP standards. PVP K series is a set of high-performance excipients widely used in pharmaceuticals and other applications, such as personal care, food, and industrial products. The characteristics of PVP K series are its high solubility, excellent film-forming properties, and outstanding binding ability. In pharmaceuticals, PVP is used as a binder in tablet formulations, thereby improving its mechanical strength and ease of production.
The K series has various levels of molecular weight available, ranging from oral solid dosage forms to injections, providing flexibility for the formulation development of a range of products. The PVP K series is also used as a stabilizer in vaccines, oral liquids, and coatings for sustained release of drug formulations. Its versatility and compatibility with a wide range of APIs make it a highly sought after excipient in the pharmaceutical industry.

Polyvinylpyrrolidone/PVP Applications
- Polyvinylpyrrolidone PVP is one of the three major new pharmaceutical excipients, which can be used as a co solvent for tablets, granules, and injections, a flow aid for capsules, a dispersant for liquid and coloring agents, a stabilizer for enzymes and thermosensitive drugs, a co precipitant for insoluble drugs, a detoxifier and lubricant for eye drops, etc.
- Polyvinylpyrrolidone PVP and its copolymer CAP are important raw materials for cosmetics, mainly used as hair styling maintenance agents. The film formed on the hair is elastic and glossy, with excellent combing performance and no dust. Different specifications of resin are used to meet various relative humidity climate conditions. Therefore, it is an indispensable raw material for styling hair cream, hair gel, and mousse.
- It can also be used as skin care moisturizer for cosmetics, hair dye dispersant for fat paste base material, and foam stabilizer to improve the consistency of shampoo.
- Polyvinylpyrrolidone PVP used in industry as a foaming agent for polystyrene, a gelling agent, stabilizer, fiber processing agent, paper processing aid, adhesive, and thickener for suspension polymerization.
- Insoluble PVP is a stabilizer for beer and fruit juice, which can improve their transparency, color, and taste
